Countable is a JavaScript function to add live paragraph-, word- and character-counting to an HTML element. Countable does not rely on any libraries and is very small in size.
You can install Countable in various ways.
- Install using bower:
bower install Countable - Clone the git repo:
git clone git@github.com:RadLikeWhoa/Countable.git - Copy the contents of the script directly
You can define your own callback function that Countable should use. If you don't pass such a function, the results are simply logged to the console.
<script src="js/Countable.js"></script>
<script>
new Countable(elem, function (counter) {
/**
* `counters.paragraphs` holds the number of paragraphs.
* `counters.words` holds the number of words.
* `counters.characters` holds the number of characters (without spaces)
* `counters.all` holds the number of characters (with spaces)
*/
alert(counter.paragraphs, counter.words, counter.characters, counters.all);
});
</script>Countable takes the value from an HTML element and counts paragraphs, words and characters (without and with spaces). Those numbers are then returned in an object, accessible by a single parameter in the callback function. In the above example, counter holds all numbers returned from Countable.
Countable has been tested in Chrome (latest), Safari (latest), Firefox (latest), Opera (latest) and Internet Explorer (7+). It is built to support both newer and older browsers.
